SPECIFICATION forming part of Letters 'Patent'No. 272,014, dated February 13, 1883.

- I Application fi1edSepteInber29,1882. (No moan.)

I being bad to the. annexed drawings, making a part of this specification. and to the letters and figures of reference marked thereon.

The object of our invention is to provide certain improvements in transmitting motion from a wind-wheel to a horizontal shalt below, allowing the wind-wheel to swivel around its perpendicular center without side resistance in the gearing, thus overcoming any tendency to turn the wind-wheel outof its true angle to the wind.

Referring to the drawings which are made a part of this specification, identical parts are designated by the same letter.

Figure l is a plan view of wind-wheel and geared attachment below. Fig. 2 is'a face view of clutch-coupling and pawls. Fig. 3 is a face view of bevel-wheel, with ratchet.

In Fig. 1, A represents the wind-wheel of a windmill; and F may be a sprocket-wheel,

chain-sheave, or pulley. c c are guide-rollers. d is a chain or connecting-belt. E is a rod connecting wind-wheelpivot q to swinging frame F, in which is hung sprocket-wheel, sheave,'or pulley g and bevel-wheel H. I and I are pinions meshing into bevel-wheel H. L is a shaft, upon which and fitted loosely thereon are hollow shaft M and bevel-wheel K, and to which are'keyed bevel-wheel 1 and clutch N. M is a hollow shaft, fitted loosely over shaft L, and to which are keyed bevel-wheel I and clutch N. y. K is a bevel-w heel fitted loosely on hollow shaft M. K is a bevel-wheel fitted loosely on shaft L. Gears K and K mesh into bevel-wheel J, which is keyed to shaft 0. It is frame upon which gearing rests.

Fig. 2 representsface of clutches N and N, which by means of pawls P mesh into ratchets of bevel-wheels K and K.

Fig. 3 represents face view of bevel-wheels K and K, representing ratchets in same.

The motion of wind-wheel A is'transmitfed from sprocket-sheave, wheel, or pulley B through chain or belt d to sprocket-sheave, or pulley g,which is attached to bevel-wheel H. Bevel-wheel H revolves bevel-wheels I and I in opposite directions, turning shafts L and M also in opposite directions. Clutches N and N, being keyed to shaftsM and L, respectively, communicate motion by means of pawls and ratchets to bevel-wheels K and K. Bevel-wheels K and K mesh into and revolve bevel-wheel J. Bevel-wheel J is keyed to shaft O,through which power may be transmitted to other machinery. The tendency of gearing to turn wind-wheel upon its pivot is overcome by bevel-wheel H meshing into bevel-wheel I at its upper side and bevel-wheel I at its lower side. Each of these two bevelwheels I and I having an equal pressure in opposite directions, and both bevel-wheels being'connected with bevel-wheel J by shafts, bevel'gears, and couplings, as described, a perfoot motion is transmitted without side-pressure. \Vhen wind-wheel A is turned to different quarters of the wind, chain or belt 61 is prevented froin twisting by rod E, connecting wheel-pivot q with revolving frame F. When wind-wheel A turns with the wind, bevelwheel H in frame F turns with it around one common center without side resistance from. gears, being allowed to so turn by means of bevel-wheels I and I, K and K, shafts L and M, and bevel-wheels H and J, arranged in such a manner as to overcome all tendency of bevel wheelsHandJtorevolvearounduprightshafts v and pawls l ge aring into ratchet in bevel- L and M, substantially as described, and for wheels Kand K, foi' the pufpnsel specified. the purpose specified.
